Granted: 1990-11-27
Abstract: Abstract of the Disclosure POLYMERIC HYPODERMIC DEVICE     There is disclosed a polymeric hypodermic device that comprises a hollow polymeric needle for injection of substances beneath the skin.  The polymeric hypodermic device is constructed of a polymeric material such as polyetheretherketones, polycarbonates, polyetherimides, polymethylpentenes, and other synthetic materials having bio-compatibility and possessing sufficient structural strength in such fine structures so as to result in penetration of the skin and adjacent body tissues.  The invention provides a novel injection end through which the medication is injected in a direction other than parallel to the axis of the needle, which has had a swirling motion imparted to it, thus lessening trauma to tissue and veins.  In addition, said injection end is conical in shape with portals above a solid conical penetrating point, the outer surfaces of the device converge uninterruptedly forward from opposite sides of a tube to a needle sharp point, above said conical penetrating point two or more portals equally spaced along the outside diameter of the device are flush with the exterior of the outer surface of the device and wherein the side walls of the portal are configured so as to impart an angular momentum to the fluid to be injected.  Another aspect of this invention is concerned with the use of such a unique polymeric needle for body fluid gathering that lessens the chances of arterial trauma and hemolysis,

Title: Process for heating materials by microwave energy
Inventor: APTE PRASAD S
IPC: H05B6/80
Filed: 1988-10-06
Granted: 1993-01-26
Abstract: Abstract:    The invention provides a process for preparing a heat-treated body from a material (preferably a dielectric ceramic) that does not couple well with microwaves while nevertheless using microwave energy for the heating step. The process involves the use of a microwave susceptor (i.e. a material that couples well with microwaves) as a means for generating heat in the material.  However, to prevent contamination of the final product with the susceptor, the susceptor is chosen from substances which following the heating step, are substantially indistinguishable from the remainder of the material forming the heat-treated body. Alpha-alumina may be heated in this way by employing sub-alpha alumina as the susceptor.  The resulting substantially pure heat-treated (and preferably sintered) bodies can be used for a variety of purposes, e.g. as substrates for micro-electronic devices.

Abstract: A composite material (22) includes droplets (24) of a liquid crystal material dispersed within a matrix (26) of a photopolymerized polymer.  The material (22) is prepared by forming a solution of the liquid crystal material and a monomer, and then polymerizing the monomer with light.  The solubility of the liquid crystal material in the polymer is less than in the monomer.  As polymerization progresses, a portion of the liquid crystal material separates as a second phase in the polymer matrix (26).  The liquid crystal can be any suitable such material that is soluble in the monomer and less so in the polymer, and the monomer is a polymerizable acrylate or methacrylate.  Liquid crystal devices are prepared by forming the composite material between two electrically conducting substrates.
